From AMESThe AMES MudRunner® makes finishing corners effortless. Just a twist of the wrist starts a continuous flow of joint compound to the attached corner finisher or mud head. Twist the handle back and the flow stops immediately.
The innovative tool uses a hydraulic piston to mechanically drive compound into the corner finisher and is capable of holding twice as much compound as a standard 8" corner applicator.
The MudRunner is ideal for finishing internal corners or for applying compound before installing paper-faced corner bead.
